We do one item per question. These will require much research, you would need to take these to an Art Appraiser to have them do research for you, then value these. I can give you a list of appraisers in your area if you would like me to answer the question in this manner. If not then you can find a local appraiser. If I find the appraisers for you, this will be your answer on this, and as such would need to be rated. If this is ok with you let me know where you are located, just a city and state.
